1 THEORY OF OPERATION
Triton® Traction Unit
1.1 OVERVIEW
The Triton traction unit is comprised of several pieces of proprietary hardware and software causing the unit
to function as required allowing administration of traction therapy under the prescription and supervision of a
licensed medical practitioner.
The Touch Screen Assembly houses the necessary hardware and software to communicate to the Motor
Control Board. Communicates commands and limits as established by the user through use of the Touch
Screen. The Touch Screen Assembly, in conjunction with the Motor Control Board, monitors the functionality
of the entire system during the course of the traction therapy being administered. Should the unit
malfunction or a communication error occur, the unit will stop treatment and generate an error message to
notify the operator of a possible problem.
The Touch Screen Assembly communicates to the Motor Control Board Assembly via a proprietary bus.
The Motor Control Board communicates to the Touch Screen Assembly throughout the therapy session all
parameters via feedback from the Motor Assembly and the Load Cell Assembly.
The Touch Screen Assembly incorporates a Patient Data Card Reader/Writer for the purpose of storing Patient
Treatment Data that can then be downloaded to a PC equipped with the optional PDMS System.

5.2 TRITON TRACTION UNIT TESTING
A. General- Electronic
1. Information within this section in respect to
electronic components is intended to aid
in troubleshooting the PCB's of the Triton units
to “Board Level” only.
These tests are the standard testing
procedures and methods used at the factory
before shipment of the unit.
2. Due to the complex nature of the technology
utilized by Chattanooga Group, the
recommended PCB troubleshooting
techniques are to determine “Bad Board” and
board replacement only. No PCB
component level troubleshooting is
recommended nor will information or parts
be supplied by Chattanooga Group. Any PC
board component level troubleshooting
performed will be at the sole risk and liability
of the Service Technician performing such
troubleshooting techniques.
3. Once a particular PCB has been
determined as bad, replace the PCB. Use
only Chattanooga Group replacement parts
and hardware.
B. General- Replacement Components
Critical component replacement parts for the
traction unit are available as subassemblies only.
This is due to the accuracy required and the
critical nature of the subassembly within the
unit for power function and operation. Individual
components of these subassemblies will not be
made available by Chattanooga Group.
C. General- Tests and Repair Procedures
1. Certain tests and repair procedures require
the use of special tools and/or fixtures.
These will be listed at the particular test
where they are required. Testing with any
other special tool or fixture other than those
stated could give erroneous readings or test
results. Always perform the tests exactly as
stated to ensure accurate results.
2. Test equipment settings will be listed for
each test performed prior to the respective
test to ensure the test is performed to
Chattanooga Group standards and ensure
power readings.
